d14 to d17 Feedback Input (Pulse input format, Encoder pulse resolution,
Pulse scaling factor 1 and Pulse scaling factor 2)
These function codes specify the speed feedback input under vector control with speed sensor.
■
Feedback Input, Pulse input format (d14)
d14 specifies the speed feedback input format.
■
Feedback Input, Encoder pulse resolution (d15)
d15 specifies the pulse resolution (P/R) of the speed feedback encoder.
• Data setting range: 20 to 60000 (P/R), Set by standard keypad using hexadecimal format (0x0014 to 0xEA60)

signal (A phase lead)
This setting is the inversion of d14 = 2. (Lead phase A Forward rotation)
In case that YA and YB are reversely connected to the specified
terminals, setting “3” to this function code can reverse the polarity of
detected speed (position) without changing the connection.
